RAPPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 497,498, dated May 16,1893.

Application filed January 22, 1892. $erial No. 418,935. (No model.)

To all whom it may concern.-

Be it known that I, EUGENE L. HOWE, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented anew and useful Improvement inRapping-Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification,

material is fed to the boxes, adjustable hammers constructed andarrangedto beat'upon the boxes so as to jar the same and to cause the settlingof the packing around the-castings, a frame-work, and means by which thehammers are actuated. "These parts, when combined as shown, form what Ibelieve to be the most desirable construction of my machine. It shouldbe understood, however, that the parts may be modified in construction,and, within the scope of my broader claims, some may be omitted orsupplied by other devices.

Referring now to the drawings, 2 represents the frame of the machine.

3 is the feed-hopper into which the packing material is charged, andfrom which it is delivered as desired in quantities regulated by meansof a suitable valve or gate (not shown) situate at the lower end.Beneath the mouth of the hopper is a secondary frame 4, of suitableform, in which opposite hammer-levers 5 are pivoted at points 6, theshorter arms of the levers being connected by a bar 7, so that when thelevers are oscillated they shall operate reciprocally in oppositedirections to beat alternately upon the box.

To oscillate the levers I employ a reciprocatoi'y rod 8 set in suitableguides and actuated by a motor through any convenient transmittingmechanism (not shown). In order to provide for the easy connection ofthe hammer-levers with the rod 8 and their disconnection therefrom, Iprovide the rod with two collars 9, and the connecting bar 7 with a hookset pivotally thereon by means of a rotatory sleeve 11 from which itprojects. When this hook is turned so as to engage the rod between thecollars, the reciprocation of the rod will cause the reciprocation ofthe bar and theoscillation of the hammer levers to which it isconnected, and when the hook is disengaged the motion of the rod willnot affect the bar. not fixed to the connecting bar, but is set looselyso as to be capable of sliding thereon. On'both sides of it are springs12 which bear against the sleeve and against collars 13, which are adjustably fixed to the rod by set-screws 14. By reason of the presence ofthese springs, the reciprocation of the'rod is transmitted to theconnecting bar not rigidly but yieldingly,

The sleeve of the hook is thus giving the hammers a freer and betteraction in their work of rapping the packingboxes hereinafterdescribcd.The box 15, in which the castings are packed, is set between thehammers, and preferably consists of three superposed separable parts I),c, and d, and in order that the hammers may be used to strike each ofthese parts,-the hammer-heads 16'are set on the levers so as to bemovable longitudinally thereon, and are provided with pawls 17, by whichthey may be adjusted and held at notches e in dilferent positions, so asto be adapted to strike the several parts of the box.

The operation is as follows:-The bottom compartment (1 is placed uponits supporting plate 18 and the hammer-heads are moved down and securedat the lowest notches on the levers. A layer of packing material is thenfed into the compartment d from the hopper, a layer of castings to beannealed is placed thereon; then more packing is introduced, and the hammer-levers are caused to oscillate and to strike against oppositesidesof the box, thereby jarring it and causing the packing material tosettle closely around the castings. In this manner alternate layers ofcastings and packing are introduced until the compartment is full, thestriking of the hammers being maintained. When this compartto beintroduced into the heating furnace.

The advantages of the machine in respect of the great saving of laborwhich it eifects t and the rapidity and efficiency with which its Workis performed will be appreciated by those skilled in the art who arefamiliar with the laborious and expensive handwork here tofore requiredfor this purpose. By reason of the fact that the hammers may be operatedcontinuously during the feeding of the packinggwhich can be introducedina thin regular streaxmthe packing can be settled and. brought intointimatecontaet with 1 every Part oi the surfaces of thecastings muchmore thoroughly than has been possible here-.

tofore. The result is that the articles are less apt-tobe distorted inform and are better annealed.

Changes in, the construction and arrange ment of the mechanism willsuggest themselves. Thus,the hammers may be alteredin. form and mode ofadjustment, mechanism other than levers. may be used to operat them, andin other respects the construction may be varied. The power used todrivethe machine may be steam power, han( i-power,

or derived from some other-suitable motor. Therefore, I do not limitmyself strictly tothe described construction, unless. the same. isexpressly included in the terms of the several claims. The machine maybe used for any purpose (other than for rappingcastings) for. whiclritis adapted.

I. claim as my invention- 1. A rapping-machine, having in combina tionwith the machine-frame, hammers arranged to strike upon the sides of thepacking-box, mechanism for actuating the same and means for feedingmaterial into the box; substantially as described.

2. A rapping-machine, having in combination, with the machine frame,hammers adapted to strike alternately upon the packing-box, mechanismfor actuating the same .and means for feeding material into the box;substantially as and for the purposes described.

3. A rapping-machine, having in combination, with the machine-framehammers arranged to strike upon the sides of the packing-box, mechanismfor actuating the same, ;and a feed-hopperabove the box support;substantially as and for the purposes described. 4.
